BACKGROUND OF THE INVENTION

1. Field of the Invention

The field of the invention is data processing, or, more specifically, methods, apparatus, and products for virtual machine administration for data center resource managers.

2. Description of Related Art

Computer systems have become highly virtualized and often support resource managers to configure, maintain, and otherwise administer a large number of resources, typically in data centers. Because the resources may vary the requirements of the virtual machine that supports the manager of those resources may also vary. It is inefficient to deploy a virtual machine with capabilities that the resource manger does not need and it is inoperable to deploy a virtual machine without the capabilities that the resource manger does need.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Exemplary methods, apparatus, and products for virtual machine administration for data center resource managers in accordance with the present invention are described with reference to the accompanying drawings, beginning with FIG. 1. FIG. 1 sets forth a block diagram of a system for virtual machine administration for data center resource managers according to embodiments of the present invention. The system of FIG. 1 includes a data center (200). A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. Data centers generally include redundant or backup power supplies, redundant data communications connections, environmental controls such as air conditioning and security devices and other computers and components as will occur to those of skill in the art.

Most of such resources in the data center may be administered by one or more resource managers deployed on one or more virtual machines administered in accordance with the present invention. A virtual machine is a software implementation of automated computing machinery, such as a computer, that executes programs like a physical machine. A virtual machine is often designed to be an efficient and isolated duplicate of a physical machine. A virtual machine as that term is used in this specification provides a complete system platform to supports the execution of a resource manager and therefore often supports a complete operating system or resources of the operation system necessary for execution of the resource manager. Such a virtual machine may be, and often is, distributed. That is, portions of virtual machines according to embodiments of the present invention may reside on multiple different physical machines.

A resource manager is a software program that administers the execution, configuration, or function of other resources both physical, such as hardware components of the data center, and logical, such as software modules executing in the data center. Such a resource manager may also be deployed in a distributed fashion on the virtual machine in accordance with the present invention. That is, the resource manager may be deployed on portions of the virtual machine which is itself deployed on more than one physical machine.

The data center (200) of FIG. 1 includes a plurality of blade environments (102). ‘Blade environment,’ as the term is used in this specification, refers generally to a blade server system installed in a chassis and including a number of resources such as blade servers, one or more blade management modules, a media tray, a blade server system power supply, fans for cooling, and other components which may be managed by a resource manager deployed on a virtual machine administered in accordance with the present invention. One example of a blade environment useful in virtual machine administration for data center resource managers according to embodiments of the present invention is the BladeCenter available from IBM®.

The data center (200) of FIG. 1 includes a plurality of other servers (106) that also include resources, both physical and logical, that may be both managed by a resource manager deployed according to embodiments of the present invention, as well as be resources upon which the virtual machine supporting the resource manager is deployed according to embodiments of the present invention.

In the example of FIG. 1, a deployment agent (124) is installed on blade environment (102 h). The deployment agent (124) is a module of automated computing machinery for virtual machine administration for data center resource managers according to embodiments of the present invention. The deployment agent (124) includes computer program instructions for virtual machine administration for data center resource managers by discovering the resources of the datacenter to be managed by the resource manager; determining, in dependence upon attributes of the resources of the datacenter to be managed, processing capabilities of the discovered resources; determining, in dependence upon attributes of the resources of the datacenter to be managed, memory capabilities of the discovered resources; determining, in dependence upon attributes of the resources of the datacenter to be managed, minimum memory requirements for managing the discovered resources; determining, in dependence upon attributes of the resources of the datacenter to be managed, minimum processing requirements for managing the discovered resources; deploying, by the deployment agent in dependence upon the determined processing capabilities and memory capabilities upon one or more of the resources of the datacenter to be managed, a virtual machine having at least the minimum memory requirements and the minimum processing requirements; and deploying, by a deployment agent, the resource manager on the virtual machine.

In the example of FIG. 1, the deployment agent (124) discovers the resources of the datacenter to be managed by the resource manager. The deployment agent may discover resources of the datacenter to be managed by, for example, sending a Service Location Protocol (‘SLP’) request over the network and receiving from various resources SLP responses. Each resource so sending an SLP response may be polled for resource identifications, capabilities, potential management requirements and other information as will occur to those of skill in the art. As mentioned above, the resources to be managed may be physical or logical. Examples of such resources include processors, input/output modules, blade servers, software components, operating systems, fans, data, databases, network resources, storage area networks, memory, and many others as will occur to those of skill in the art.

In the example of FIG. 1, a virtual machine supporting the resource manager is deployed on one or more of the resources of the data center itself. As such, some resources managed by the resource manager provide computing contributions to the virtual machine—not just consumption—and therefore in virtual machine administration according to the present invention, those resource contributions are taken into consideration along with resource consumptions when deploying an appropriate virtual machine for the resource manager.

The deployment agent (124) of FIG. 1 also determines in dependence upon attributes of the resources of the datacenter to be managed processing capabilities and memory capabilities of the discovered resources. Attributes of the resource may include the type and kind of the resource, manufacturer ratings of the resource. The type of capabilities for the resource, the type of management requirements for the resource, the uses of the resource, any many others as will occur to those of skill in the art.

In some embodiments of the present invention, the deployment agent may poll each resource selected for management by the resource manager for its processing capabilities and its memory capabilities. In some alternative embodiments, the deployment agent may maintain a list of identifications of resources and their processing capabilities and their memory capabilities.

Turning briefly to FIG. 2, FIG. 2 sets forth a table (800) of resource contributions of the example resources discovered. In the example of FIG. 2, the table (800) includes descriptions of the discovered resources (802) and the number (804) of how many of each type of resources was discovered. In the example of FIG. 2, three fans of ‘Fan Type A’ were discovered, six fans of ‘Fan Type B’ were discovered, four software module called ‘Software Module A’ were discovered, two compute nodes were discovered, five I/O modules were discovered and one external storage area network was discovered.

The table (800) of FIG. 2 also includes the processor contributions (806) and memory contributions (808) that will benefit the virtual machine supporting the resource manager managing each of the discovered resources. In the example of FIG. 2, a Type A fan contributes no FLOPS of processor capability and no memory capability for a virtual machine. In the example of FIG. 2, a Type B fan contributes no FLOPS of processor capability and no memory capability for a virtual machine. The discovered software module of the type of ‘Software Module A’ contributes no FLOPS of processor capability and no memory capability for a virtual machine. The discovered compute node contributes 100000 FLOPS of processor capability and 400000 bytes of memory capability to a virtual machine. In the example of FIG. 2, an I/O module contributes no FLOPS of processor capability and no memory capability for a virtual machine. And the discovered external SAN contributes no FLOPS of processor capability and no memory capability for a virtual machine. Having determined the processor contributions and memory contributions of each type of discovered resources and the total number of each type of discovered resource a deployment agent may calculate the total processor contributions and the total memory contribution capable of being provided to a virtual machine by the discovered resources.

Again with reference to FIG. 1: The example deployment agent (124) of FIG. 1 determines the memory capabilities and processing capabilities for contribution to a virtual machine deployed on one or more of the resources of the data center (200). Typically the deployment agent (124) determines the memory capability and processing capability in dependence upon the processing and memory contributions of each type of discovered resource and the number of such resources discovered.

The deployment agent (124) of FIG. 1 also determines, in dependence upon attributes of the resources of the datacenter to be managed, minimum memory requirements and minimum processing requirements for managing the discovered resources. Attributes of the resource may include the type and kind of the resource, manufacturer ratings of the resource, the type of management requirements for the resource, the uses of the resource, any many others as will occur to those of skill in the art. In some embodiments of the present invention, the deployment agent may poll each resource selected for management by the resource manager for its minimum processing requirements and its minimum memory requirements. In some alternative embodiments, the deployment agent may maintain a list of identifications of resources and their processing requirements and their memory requirements.

Turning briefly to FIG. 3, FIG. 3 sets forth a table (700) of resource requirements of some example resources capable of being discovered and capable of being managed by a resource manager in accordance with the present invention. In the example of FIG. 3, the table (700) includes descriptions of the discovered resources (702) and the number (704) of how many of each type of resources was discovered. In the example of FIG. 3, three fans of ‘Fan Type A’ were discovered, six fans of ‘Fan Type B’ were discovered, four software module called ‘Software Module A’ were discovered, two compute nodes were discovered, five I/O modules were discovered and one external storage area network was discovered.

The table (700) of FIG. 3 also includes the processor requirements (706) and memory requirements (708) for managing each type of discovered resources. In the example of FIG. 3, a Type A fan requires 300 floating point operations per second (‘FLOPS’) of processor capacity and 2 bytes of memory capacity to manage that type of discovered fan. In the example of FIG. 3, a Type B fan requires 150 FLOPS of processor capacity and 2 bytes of memory capacity to manage that type of discovered fan. The discovered software module of the type of ‘Software Module A’ requires 3000 FLOPS of processor capacity and 8000 bytes of memory capacity to manage that type of discovered software module. The discovered compute node requires 1000 FLOPS of processor capacity and 4000 bytes of memory capacity to manage that type of compute node. In the example of FIG. 3, an I/O module requires 500 FLOPS of processor capacity and 1000 bytes of memory capacity to manage that type of I/O module. And the discovered external SAN requires 1000 FLOPS of processor capacity and 2 bytes of memory capacity to manage that type of storage area network. Having determined the processor capacities and memory capacities of each type of discovered resources and the total number of each type of discovered resource a deployment agent may calculate the total minimum processor requirements and the total minimum memory requirements for managing the totality of discovered resources.

Again with reference to FIG. 1: The deployment agent (124) of FIG. 1 determines the minimum memory requirements and minimum processing requirements for managing all of resources selected for management by a particular resource manager. The deployment agent (124) typically determines the minimum memory requirements and minimum processing requirements in dependence upon the processing and memory requirements of each type of discovered resource and the number of such resources discovered.

In the example of FIG. 1, deployment agent (124) deploys a virtual machine having at least the minimum memory requirements and the minimum processing requirements onto one or more resources of the data center. The deployment agent (124) deploys the virtual machine upon selected resources in dependence upon the determined processing capabilities and memory capabilities contributed by the discovered resources. The deployment agent of FIG. 1 typically deploys a virtual machine having at least the minimum memory requirements and the minimum processing requirements by selecting one or more resources in the data center that together have the minimum memory requirements and the minimum processing requirements and deploying the virtual machine on the selected resources. In the example of FIG. 1 the a first portion of the virtual machine (120 a) is deployed on blade environment (102 j), a second portion of the virtual machine (120 b) is deployed on server (106 a), and a third portion of the virtual machine (120 c) is deployed on server (106 a).

The deployment agent of FIG. 1 may also deploy a virtual machine or a portion of the virtual machine to resources having appropriate cooling capability. In such embodiments, the deployment agent identifies minimum cooling requirements for the virtual machine and selects resources in the datacenter upon which to deploy at least a portion of the virtual machine and resource manager in dependence upon those minimum cooling requirements.

In the example of FIG. 1, deployment agent (124) deploys a resource manager on the virtual machine. In the example of FIG. 1, the resource manger is shown executing on the third portion (120 c) of the virtual machine on server (106 a). The blade environments, servers, deployment agent locations, locations of the deployed virtual machine, and resource manager are provided for explanation and not for limitation. In fact, virtual machine administration for data center resource managers may include many different resources and different configurations of virtual machines deployed on those resources as will occur to those of skill in the art.

The arrangement of servers and other devices making up the exemplary system illustrated in FIG. 1 are for explanation, not for limitation. Data processing systems useful according to various embodiments of the present invention may include additional servers, routers, other devices, and peer-to-peer architectures, not shown in FIG. 1, as will occur to those of skill in the art. Networks in such data processing systems may support many data communications protocols, including for example TCP (Transmission Control Protocol), IP (Internet Protocol), HTTP (HyperText Transfer Protocol), WAP (Wireless Access Protocol), HDTP (Handheld Device Transport Protocol), and others as will occur to those of skill in the art. Various embodiments of the present invention may be implemented on a variety of hardware platforms in addition to those illustrated in FIG. 1.

For further explanation, FIG. 4 sets forth a diagram of a further example data processing system useful in virtual machine administration for data center resource managers according to embodiments of the present invention. The example data processing system of FIG. 4 includes a blade environment (102), blade servers (124) connected through an internal LAN (101) to a blade management module (152), fans (155), a media tray (122) connected to the blade management module all resources capable of being managed by a resource manager deployed in accordance with the present invention. In addition, FIG. 4 includes a functional block diagram showing detail of the blade management module (152). The blade management module (152) of FIG. 1 includes at least one computer processor (156) or ‘CPU’ as well as random access memory (168) (‘RAM’) which is connected through a high speed memory bus (166) and bus adapter (158) to processor (156) and to other components of the blade management module (152).

The deployment agent (124) is capable of discovering resources of the datacenter to be managed by a resource manager; determining, by in dependence upon attributes of the resources of the datacenter to be managed, processing capabilities of the discovered resources; determining, in dependence upon attributes of the resources of the datacenter to be managed, memory capabilities of the discovered resources; determining, in dependence upon attributes of the resources of the datacenter to be managed, minimum memory requirements for managing the discovered resources; determining, in dependence upon attributes of the resources of the datacenter to be managed, minimum processing requirements for managing the discovered resources; deploying, by the deployment agent in dependence upon the determined processing capabilities and memory capabilities upon one or more of the resources of the datacenter to be managed, a virtual machine having at least the minimum memory requirements and the minimum processing requirements; and deploying the resource manager on the virtual machine.

Also stored in RAM (168) is an operating system (154). Operating systems useful for virtual machine administration for data center resource managers according to embodiments of the present invention include UNIX™, Linux™, Microsoft Windows XP™, Microsoft Vista™, AIX™, IBM's i5/OS™, and others as will occur to those of skill in the art. The operating system (154) and the deployment agent (124) in the example of FIG. 4 are shown in RAM (168), but many components of such software typically are stored in non-volatile memory also, such as, for example, on a disk drive or in firmware (136) on an EEPROM drive, here shown as flash memory (134).

The exemplary blade management module (152) of FIG. 4 includes one or more input/output (‘I/O’) adapters (167). I/O adapters implement user-oriented input/output through, for example, software drivers and computer hardware for controlling output to display devices such as computer display screens, as well as user input from user input devices (181) such as keyboards and mice.

The exemplary blade management module (152) of FIG. 4 also includes a communications adapter (169) that couples the blade management module (152) internally within the blade environment (102) for data communications with blade servers (124) through a local area network (101) and externally to the data center management module (200). The networks (101) may be implemented, for example, as an Internet Protocol (‘IP’) network or an Ethernet™ network, an I²C network, a System Management Bus (‘SMBus’), an Intelligent Platform Management Bus (‘IPMB’), for example, and in other ways as will occur to those of skill in the art. Such a communications adapter (169) are electronic modules that implement the hardware level of data communications through which one computer sends data communications to another computer through a data communications network. Examples of communications adapters useful according to embodiments of the present invention include modems for wired dial-up communications, Ethernet (IEEE 802.3) adapters for wired data communications network communications, and 802.11 adapters for wireless data communications network communications.

The arrangement of the blade management module (152), the blade servers (124), and other devices making up the exemplary system illustrated in FIG. 4 are for explanation, not for limitation. Data processing systems useful according to various embodiments of the present invention for virtual machine administration for data center resource managers may include additional servers, routers, and other devices, not shown in FIG. 4, as will occur to those of skill in the art. Data processing systems useful according to various embodiments of the present invention for virtual machine administration for data center resource managers may also include different computers and servers and may take many different form factors. Networks in such data processing systems may support many data communications protocols, including for example TCP (Transmission Control Protocol), IP (Internet Protocol), HTTP (HyperText Transfer Protocol), WAP (Wireless Access Protocol), HDTP (Handheld Device Transport Protocol), and others as will occur to those of skill in the art. Various embodiments of the present invention may be implemented on a variety of hardware platforms in addition to those illustrated in FIG. 4.

For further explanation, FIG. 5 sets forth a flow chart illustrating an exemplary method for deploying a virtual machine for a resource manager of a data center according to embodiments of the present invention. Then method of FIG. 5 includes discovering (402), by a deployment agent, the resources of the datacenter to be managed by the resource manager. As mentioned above, the resources of the data center capable of being managed by the resource manager may be physical resources of the datacenter or logical resources of the datacenter. Examples of such resources include processors, input/output modules, blade servers, software components, operating systems, fans, data, databases, network resources, storage area networks, memory, and many others as will occur to those of skill in the art.

Discovering (412), by a deployment agent, the resources of the datacenter to be managed by the resource manager may be carried out by through sending a request to resources on a network and receiving responses to the request such as through the use of SLP or WS-Discovery. The Service Location Protocol (‘SLP’) is a resource discovery protocol that allows computers and other devices to find resources in a network without prior configuration. Web Services Dynamic Discovery (WS-Discovery) is a technical specification that defines a multicast discovery protocol to locate resources on a network. For example, discovering the resources of the datacenter to be managed by the resource manager may be carried out sending a Service Location Protocol (‘SLP’) request over the network and receiving from various resources SLP responses. Each resource so sending an SLP response may be polled for resource identifications, capabilities, potential management requirements and other information as will occur to those of skill in the art. The resources may then be selected for management and may be selected based upon the a number of factors such as type of resource to be managed, the ownership of the resource, the number of the type of resource or any other factor that will occur to those of skill in the art.

The method of FIG. 5 also includes determining (412), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, processing capabilities of the discovered resources. In some embodiments, determining (412), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, processing capabilities of the discovered resources may be carried out by polling each resource for the processing capabilities of the resource. In some other embodiments, determining (412), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, processing capabilities of the discovered resources may be carried out by from a list or other data structure the processing capabilities of the resource.

In some embodiments, determining (414), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, memory capabilities of the discovered resources may be carried out by polling each resource for attributes of the resource that describe the memory capabilities of the resource. In some other embodiments, determining (414), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, memory capabilities of the discovered resources may be carried out by retrieving from a list or other data structure the memory capabilities of the resource.

The method of FIG. 5 includes determining (408), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, minimum memory requirements for managing the discovered resources. In some embodiments of the present invention, determining (408), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, minimum memory requirements for managing the discovered resources may be carried out by polling each resource for its memory requirements. In some other embodiments of the present invention, determining (408), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, minimum memory requirements for managing the discovered resources may be carried out retrieving from a list or other data structure the minimum memory requirements for managing the discovered resources. In other embodiments, determining (408) minimum memory requirements for managing the discovered resources may be carried out by calculating the memory requirements in dependence upon known factors such as physical architecture, network capabilities of the data center, physical layout of the data center, software available to the deployment agent and other factors that will occur to those of skill in the art.

The method of FIG. 5 also includes determining (410), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, minimum processing requirements for managing the discovered resources. In some embodiments of the present invention, determining (410), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, minimum processing requirements for managing the discovered resources may be carried out by polling each resource for its processing requirements. In some other embodiments of the present invention, determining (410), by the deployment agent in dependence upon attributes of the resources of the datacenter to be managed, minimum processing requirements for managing the discovered resources may be carried out by retrieving from a list or other data structure the processing requirements for the discovered resources. In other embodiments, determining (410) minimum processing requirements for managing the discovered resources may be carried out by calculating the memory requirements in dependence upon known factors such as physical architecture, network capabilities of the data center, physical layout of the data center, software available to the deployment agent and other factors that will occur to those of skill in the art.

The method of FIG. 5 includes deploying (416), by the deployment agent in dependence upon the determined processing capabilities and memory capabilities upon one or more of the resources of the datacenter to be managed, a virtual machine having at least the minimum memory requirements and the minimum processing requirements. Deploying (416), by the deployment agent in dependence upon the determined processing capabilities and memory capabilities upon one or more of the resources of the datacenter to be managed, a virtual machine having at least the minimum memory requirements and the minimum processing requirements is carried out by selecting one or more resources in the data center meeting the minimum memory and minimum processing requirements of the virtual machine and instantiating a virtual machine on the selected resources.

Deploying (416), upon one or more of the resources of the datacenter to be managed, a virtual machine having at least the minimum memory requirements and the minimum processing requirements may be carried out by selecting one or more resources in the data center that together have the minimum memory requirements and the minimum processing requirements and deploying the virtual machine on the selected resources. Deploying (416), upon one or more of the resources of the datacenter to be managed, a virtual machine having at least the minimum memory requirements and the minimum processing requirements may also be carried out by identifying, in dependence upon at least the minimum processing requirements for managing the discovered resources, minimum cooling requirements for the virtual machine; and selecting resources in the datacenter upon which to deploy at least a portion of the virtual machine and resource manager in dependence upon the minimum cooling requirements. Such cooling requirements may be met by selecting resources with heat sinks, fans, or other devices capable of cooling the resource such that the resource may meet the minimum processing requirements of the virtual machine.

The method of FIG. 5 also includes deploying (418), by a deployment agent, the resource manager on the virtual machine. Deploying (418), by a deployment agent, the resource manager on the virtual machine may be carried out by instantiating a resource manager for the discovered resources on the virtual machine.
